THOMAS A. QUINN, OF YONKERS, NEV YORK.

SPECIFICATION forming part of Letters Pa 784,277, dated March '7, 1905.

Application filed July 5, 1904. Serial No. 215,205.

To all whom it may concern:

Be it known that l, THOMAS A. QUINN, a citizen of the United States,residing at Yonkers, in the county of lVestchester and State of NewYork, have invented certain new and useful Improvements in ReversingGears for Mandrels or other Shafts, of which the following is aspecification, such as will enable those skilled in the art to which itappertains to make and use the same.

The object of this invention is to provide an improved reversing-gearwhereby the mo tion of a driven shaft may be conveniently reversed atany time and the direction of a mandrel or other shaft geared inconnection therewith also reversed whenever desired and whereby thespeed of said shafts may be increased or decreased as the motion thereofis reversed; and with this and other objects in view the inventionconsists in an apparatus of the class specified constructed ashereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof rnyimprovement are designated by suitable reference characters ineach of the Views, and in which Figure 1 is a longitudinal section of myimproved reversing-gear apparatus; Fig. 2, a section on the line 2 2 ofFig. 1, and Fig. 3 a section on the line 3 3 of Fig. 1.

In the drawings forming part of this specification I have shown at a adriven shaft, which in practice is driven by a main powershaft (notshown) and geared in connection with a pulley 7), loosely mounted on thedriven shaft (1, by means of a belt or similar device, which is also notshown. I have also shown at c a mandrel or similar shaft, and the drivenshaft a is provided with a cone-pulley a and the mandrel-shaft c with asimilar cone-pulley c and these pulleys are geared in connection bymeans of a belt (Z.

Mounted on the driven shaft 0, at the right of the pulley t and movablelongitudinally on said shaft, is a clutch-disk 6, provided with a hub eand a flange or rim 0 adapted to operate within and upon the adjacentflange or rim of the pulley 7), and suspended from any suitable supportfis a hanger f which is pivotally connected with a supplementalyokeshaped supportf connected with the support f and which is adapted toswing longitudinally of the driven shaft, and the hanger-f is providedwith a collar f, having side pins f one of which is shown in dottedlines in Fig. 1, and the pins f operate in an annular groove 0* in thehub e of the disk 0, and said hanger is also provided with a dependinghandle portion f, by which it may be operated and the disk 6 movedtoward and from the pulley b.

At the left-hand side of the pulley is another hanger, g, suspended fromany suitable support provided with the yoke-shaped supplemental supportg, with which the hanger g is pivotally connected, and said hanger isprovided with a collar 1", through which the driven shaft (0 passes.

Mounted on the driven shaft (0, at the left of the pulley 7) and movableon said shaft, is a gear-disk h, having a hub 7f, which also passesthrough the collar g" of the hanger g and is provided with trunnions h,which pass outwardly through the opposite sides of the collar g, and inthe form of construction shown the hangers f and g are made of separatepieces of strap-iron bolted together, as shown at 2', and in Fig. 1 thesection-line passes between the separate parts of these hangers, and thebolts are shown in section between the top and bottom portions of saidhangers, and the lower ends of said hangers are connected by a link orrod j, parallel with the driven shaft (0 and one of said hangers. Thatat the right of the pulley b in the form of construction shown isprovided with a handle Z, by which both of said hangers may be operated.

Mounted on the d riven shaft, adjacent to the pulley b, is a gear-wheelm, which is of much less diameter than said pulley, and secured to theperimeter of the disk h is a clutch flange or rim '12, which extends inthe direction of the pulley b and is adapted to operate within and uponthe corresponding flange or rim of said pulley, and said clutch flangeor rim is provided with an internal gear 02 and between the clutchflange or rim a and the gear-wheel on and at opposite points in theconstruction shown are two pinions 0, which are connected with the disk72 by suitable spindles or bolts which in the form of construction shownare made in the manner of screws and screwed into and'through the diskIt and held in place by nuts 9 and said pinions 0 mesh with thegearwheel m and with the internal gear a of the clutch flange or rim 02.

The clutch flange or rim n in the form of construction shown isconnected With the disk h, as shown in Fig. 1, saiddisk being providedin its perimeter with an annular groove 71, in which is placed aring orband 9*, and the clutch flange or rim n is provided in the inner face ofthe base portion thereof with an annular groove a, and the ring or band1 and the clutch flange or rim are bolted or screwed together, as shownat 0 The operation will be readily understood from the foregoingdescription when taken in connection with the accompanying drawings andthe following statement thereof. It will be understood that the pulley bin practice is driven by means of a belt from a main powershaft, ashereinbefore stated, said powershaft and belt being not shown, and ifthe hangers f and g be swung to the left the clutch e or the rim orflange 6 thereof will engage the pulley b and the driven shaft (0 willbe turned in the same direction as the main power-shaft. If the hangersf and g be swung to the right, the disk 0 or the flange or rim 0 thereofwill be disconnected from the pulley b and the clutch flange or rim n ofthe disk It will engage said pulley, as shown in Fig. 1, and the motionof the shaft (0 will be reversed, and the speed of the shaft a will beless when moving in this direction than when driven by the disk 6.

It will be understood that the reversal of the shaft a is occasioned bythe pinions 0 operating in connection with the gear-wheel m, and therelative sizes of these pinions and said gear-wheel will also determineto an extent the speed of the shaft 0, and it is also evident that oneof the pinions 0 would be sufficient to operate the shaft a; but byemploying two of said pinions in the manner shown and described theapparatus is balanced and the operation thereof rendered more even anduniform and the friction and strain on the parts is reduced.

My improved reversing-gear may be employed wherever apparatus of thisclass is desired, and changes in and modifications of theconstruction-thereof as herein described may be made without departingfrom the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is
